Divorce searches in Dallas County and Collin County are not the same market
The Metroplex is not one search market, and treating it as one is the reason a single broad page stalls.
People rarely search for a lawyer without attaching a place. They type a suburb, a county, or the neighborhood they live in. A firm in Uptown and a firm in Plano are competing for overlapping but different query sets, and the overlap is smaller than most owners assume.
Filing county matters to the buyer more than it matters to most marketers. Someone in Frisco wants to know whether their case runs through Collin County or Denton County, because their address decides it and their address sits near a line. Local practice varies by court and is worth confirming with the district clerk or your own counsel, but a page that names the county and explains what filing there involves reads as written by someone who goes there.
Build one page for each county you actually appear in. Not each city you would like to serve. Four honest county pages outperform twenty thin city pages with the name swapped, and search engines have been unkind to the swapped-name approach for years.
The test for whether a page deserves to exist is simple. If an attorney at your firm could not add three sentences to it that a competitor would not have written, the page is filler.
